Friendship is about far more than being alike in this simple yet satisfying story. Zack and Ike are best friends who like to think they're exactly alike.   They have the same backpack, the same bike, and the same kind hearts. But what happens when these best friends disagree? And what happens when they meet a new friend who is exactly different--or is she?   In this classic friendship story written by award-winning author Suzanne Bloom, readers will see that Zack and Ike are alike in some ways, but different in others--and that's okay! Because you don't have to be exactly alike to be friends.
